This paper proposes a low power multi-Lane Mobile Industry Processor Interface (MIPI) Camera Serial Interface 2 (CSI-2) receiver architecture which adopts an 8-Byte parallel CSI protocol layer for hardware implementations. The proposed scheme can work in environment with 4 data Lanes and 1 Gb/s per data Lane, i.e. with maximum data rate 4 Gb/s, at 62.5 MHz which increases logic operations from 8 ns (125 MHz) to 16 ns (62.5 MHz) without throughput degradation. Therefore, the supply voltage (1.2 V) can be reduced and the power consumption can also be reduced. The proposed architecture is implemented by 0.13μm CMOS technology and the total gate count is 32.7K. It not only reduces the operating clock rate but also reduces more than 37%∼43% logic power consumption measured in chip.
